ROTARY MOTOR.

Specification of Letters Patent.

Patented Nov. 25, 1913.

Application filed February 24, 1913. Seria1No.'750,320.

To all whom it may concern:

Be it known that I, ARTHUR J. KRoUsE, a subject of the Emperor of Austria-Hungary, residing at Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Rotary Motors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends improvements in motors of the turbine type and relates more particularly to motors having rotors or pistons formed by spiral ribs.

The primary object of the invention resides in the provision of a motor of this type, which is so constructed as to utilize the full power of the motive agent, this being accomplished by forming the coils of the ribs relatively close to one another so that the motive agent will frictionally engage the same, and by obstructing the passage of the steam around the rotor by means of slotte baffie plates.

Another object of the invention resides in tne provision of a rotor of such construction as to cause the motive agent to act principally upon those portions of the spiral grooves which lie adjacent the periphery of the rotor.

The invention also aims to provide novel means for admitting a motive agent into the motor and for conducting the same therefrom.

With these and other objects in View, as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which,

Figure 1 is an end elevation of avrotary motor constructed in accordance with my invention, the casing end being partly broken away and parts of the motor being shown in section, Fig. 2 is a top plan view of my improved motor, shown partly in section, Fig. 3 is a side elevation, Fig. 4: is a side elevation of the rotor, Fig. 5 is a detail sectional view of the rotor illustrating the passage of the steam between the coils thereof, Fig. 6 is a fragmentary sectional vlew taken through the rotor on a plane at right angles to the axis thereof, Fig. 7 is a detail sectional view showingthe construction of the main intake valve and the cooperating parts, and, Fig. 8 is a longitudinal sectional view through one of the valves to be described later, and taken on the plane of line 8-8 of Fig.

In the following description and accompanying drawings, similar parts will be referred to and designated by like reference characters.

Referring in detail to the drawings by numerals, 10 designates a cylindrical casing having the end walls 11, which are removable. The casing is supported upon any suitable foundation 12. A shaft 13 extends through the walls 11 and through bearings 14 which are secured within centrally positloned openings formed in said walls, the bearings being provided with oil cups 15 which are preferably formed integral therewith and which communicate with the interior of the bearings by means of the passages 16. A rotor, generally designated 17 is fixed to the shaft 13 and is adapted to rotate the same. The rotor includes a hub 18, a spiral rib 19 which extends the entire length of the hub, and a plurality of baffle or division plates 20. The rib 19 forms coils of a much larger diameter than the hub 18 and said coils are positioned rat-her close to one another so that the spiral passage through the same is quite narrow. The battle plates 20 extend radially from the hub to the periphery of the rotor and are arranged at equal distances along the passage between the coils of the rib. As clearly shown in Fig. 4, this arrangement of bafile plates provides a number of series and the plates of each series are disposed in one of the planes which passes longitudinally through the center of the hub. Each baffle plate 18 recessed along one of its longitudinal edges adjacent its outer end, as indicated at 21 and these recesses are arranged in staggered relationship in the passage between the coils formed by the ribs. This construction is clearly shown in Fig. 5.

The rotor is fitted within the casing 10 and engages the interior thereof so that the entire amount of motive agent which is admitted to said chamber must flow through the passage formed by the spiral rib. The hub 18 is formed with the bearing cups'22 which fit over the bearings 14, thus supporting the rotor. The motive agent is cona one end of the rotor.

ducted to the casing 10 by means ofa main pipe 23 and branch pipes 24 and 25, said last mentioned pipes opening tangentially.

into said casing ad acent opposite ends:

thereof, as indicated at 26. Branch exhaust pipes 27 and 28 also communicate with the interior of the casing through the openings 26 and are connected at their extremities valve 30 is'positioned at the juncture of the mainland branch intake pipes and is adapted to direct the motive agent into either of the branch pipes or to stop the flow of the same entirely. Frusto-conical valves 31 extend through the intake .and exhaust to a main exhaust pipe 29. A frusto-conical' pipes, as shown in Fig. 2. These valves are} formedzadjacent their smaller ends with the passages 32 which permit the motive agent .to flow into the cylinder, and are formed adjacent their larger ends with the passagesg 33 which permit the motive agent to exhaust from "the casing. The passages 32 and 33 extend at right angles to one another so that when the passage through one of the branch pipes is opened the passage;

through the corresponding branch pipe.

is closed, .and when, for instance, pas

sage through the branch pipe 24 is opened :the passage through the exhaust pipe 27 is closed. The valves 31 are simultaneously actuated by means of a lever '34 and links 35 and 36. The valve 30 is operated .to allow the steam to pass through either of'the branch pipes 24 and 25. The entrance to the .branch pipe not in use is will flowthrough the spiral passage formed connection with the accompanying drawings, it will be seen that I have .designed a rotary motor which will generate a relatively large amount of power, which is simple in construction, which may be made large enough to furnish any :amount of power,

and which may also be constructed of a size suitable for toys.

It is to be understood that while I have shown and described the preferred embodiment of my invention, I do not wish to be limited 'to this exact construction, combination, and arrangement of parts, but may make such changes as will fall within the spirit and scope .of the invention.

Having thus described any invention, what I claim is.:

In a rotary unotor of the character described,.a rotor comprising a hubof .a relatively small diameter, a spiral rib extending the full length of said hub and forming a narrow spiral passage, and .baflie plates arranged throughout the entire length of said passage and extending radially from the hub to the periphery of the rotor, said bafl'le plates being recessed along certain of their side edges adjacent their outer ends, the recesses being positioned .in staggered relationship within the passage.

In testimony whereof Iaflix .my signature in presence of two witnesses.
